Title: Noise Simulation of Continuous Integrator and SC Amplifier Post by analog_design on May 12th, 2011, 11:42pm Hi Guys, I am really facing problem while doing noise simulation of Continuous TIme Integrator. I am using Spectre simulatior Which is correct method to do noise simulation ? noise in ADE or PSS, PAC and Pnoise Please, explain me detail steps to do noise simulation. I have done analysis with above method. but, I am not confidence whether it is correct or not ? If you have any doc or suggested book on noise simulation / analysis then please let me know. Thank You. |
Title: Re: Noise Simulation of Continuous Integrator and SC Amplifier Post by sheldon on May 13th, 2011, 8:51pm Analog Design, It would help if you would explain what your problem is. Is your problem that you don't know which tool to use? How to use the tools? The results are not consistent with hand calculation? The results are not consistent with measurement? ...? Next, sorry I am a little bit slow. Why would you be using periodic steady-state analysis to analyze a continuous time integrator? Does the integrator have reset? Is it used inside a loop, for example, the controller in a dc-to-dc converter? Also some comments: 1) ADE is the simulation environment and Spectre is the simulator 2) Spectre performs both linear noise and periodic noise analysis 3) Manages the pre-simulation setup and post-simulation analysis Best Regards, Sheldon |
Title: Re: Noise Simulation of Continuous Integrator and SC Amplifier Post by analog_design on May 18th, 2011, 8:57am Hi Sheldon, I am sorry I have passed incomplete information. Please go through an attached block diagram. after resistor there is one MOSFET switch. this is kind of design of integrator. Resistor is fixed. instead of DAC i am using fixed bias for time being. Please, let me know how can characterize / analysis this design like Noise simulation, Time domain analysis. Is correct way to do small signal noise simulation in cadence or PSS, PAC and Pnoise simulation. Please, let me know in detail. I would be thankful to you. Warm Regards, Analog_Design |
